C :

#include "stdio.h"
 
int main() {
    int year1, year2;
    // 输出格式是%lu,所以数据类型是无符号长整形
    unsigned long count = 0;
    // 闰年心跳总数
    unsigned long num1 = 75 * 60 * 24 * 366;
    // 平年心跳总数
    unsigned long num2 = 75 * 60 * 24 * 365;
    scanf("%d", &year1);
    scanf("%d", &year2);
    int i ;
    for(i = year1; i < year2; ++i){
        if ((i % 4 == 0 && i % 100 != 0) || i % 400 == 0) {
            count += num1;
        }else{
            count += num2;
        }
    }
    printf("The heart beats in your life: %lu", count);
}
